# Continuous Integration (CI)
|
|
|
|
## 매 한 줄
|
|
> **"매 push마다 build + test, fast feedback"**. Grady Booch (1991) 가 제안, Martin Fowler 가 대중화. 2026 현재 GitHub Actions / GitLab CI 가 표준이며, AI-assisted PR review (Claude Opus 4.7) 와 결합되어 매 commit 검증 cycle 이 분 단위로 압축됨.
|
|
|
|
## 매 핵심
|
|
|
|
### 매 원칙
|
|
- **Mainline integration 빈번**: 매 developer 매일 main 에 merge.
|
|
- **Automated build**: 매 commit trigger build pipeline.
|
|
- **Automated test**: unit + integration + lint 매 자동 실행.
|
|
- **Fast feedback**: <10 min 안에 결과. 길어지면 dev 매 ignore.
|
|
- **Single source of truth**: 매 single repo, single mainline.
|
|
|
|
### 매 stages
|
|
- **Lint** (10s) — eslint, ruff, gofmt.
|
|
- **Unit test** (1-3 min) — vitest, pytest, go test.
|
|
- **Integration test** (3-8 min) — testcontainers, ephemeral DB.
|
|
- **Build artifact** (1-2 min) — docker image, npm tarball.
|
|
- **Static analysis** (parallel) — SonarQube, Snyk, CodeQL.
|
|
|
|
### 매 응용
|
|
1. SaaS product 매 trunk-based development.
|
|
2. Open-source project 매 PR validation.
|
|
3. Monorepo 매 affected-only build (Turborepo, Nx).
|
|
|
|
## 💻 패턴
|
|
|
|
### Modern GitHub Actions (2026)
|
|
```yaml
|
|
name: CI
|
|
on:
|
|
push: { branches: [main] }
|
|
pull_request:
|
|
merge_group:
|
|
|
|
concurrency:
|
|
group: ${{ github.workflow }}-${{ github.ref }}
|
|
cancel-in-progress: true
|
|
|
|
jobs:
|
|
test:
|
|
runs-on: ubuntu-24.04
|
|
steps:
|
|
- uses: actions/checkout@v5
|
|
- uses: actions/setup-node@v5
|
|
with: { node-version: '22', cache: 'pnpm' }
|
|
- run: pnpm install --frozen-lockfile
|
|
- run: pnpm lint
|
|
- run: pnpm test --coverage
|
|
- uses: codecov/codecov-action@v5
|
|
```
|
|
|
|
### Matrix build
|
|
```yaml
|
|
strategy:
|
|
fail-fast: false
|
|
matrix:
|
|
os: [ubuntu-24.04, macos-14, windows-2022]
|
|
node: [20, 22]
|
|
runs-on: ${{ matrix.os }}
|
|
```
|
|
|
|
### Affected-only (monorepo)
|
|
```yaml
|
|
- run: pnpm exec turbo run test --filter=...[origin/main]
|
|
```
|
|
|
|
### Reusable workflow
|
|
```yaml
|
|
# .github/workflows/reusable-test.yml
|
|
on:
|
|
workflow_call:
|
|
inputs:
|
|
node-version: { type: string, default: '22' }
|
|
jobs:
|
|
test:
|
|
runs-on: ubuntu-24.04
|
|
steps: [ ... ]
|
|
```
|
|
|
|
### Container-based test (testcontainers)
|
|
```python
|
|
# pytest with ephemeral postgres
|
|
from testcontainers.postgres import PostgresContainer
|
|
|
|
def test_repo():
|
|
with PostgresContainer("postgres:17") as pg:
|
|
url = pg.get_connection_url()
|
|
# run integration test against real DB
|
|
```
|
|
|
|
### Cache layers (docker buildx)
|
|
```yaml
|
|
- uses: docker/build-push-action@v6
|
|
with:
|
|
context: .
|
|
cache-from: type=gha
|
|
cache-to: type=gha,mode=max
|
|
tags: ghcr.io/org/app:${{ github.sha }}
|
|
```
|
|
|
|
### AI PR review (2026)
|
|
```yaml
|
|
- uses: anthropic-experimental/claude-code-action@v1
|
|
with:
|
|
api-key: ${{ secrets.ANTHROPIC_API_KEY }}
|
|
model: claude-opus-4-7
|
|
review-mode: pr-comment
|
|
```
|
|
|
|
## 매 결정 기준
|
|
| 상황 | Approach |
|
|
|---|---|
|
|
| Open-source GitHub repo | GitHub Actions |
|
|
| Self-hosted, private | GitLab CI / Drone |
|
|
| Monorepo | Turborepo + affected-only |
|
|
| Polyglot, complex | Buildkite / Bazel |
|
|
| Mobile (iOS/Android) | Bitrise / Xcode Cloud |
|
|
|
|
**기본값**: GitHub Actions + concurrency cancel + matrix + cache.

## 🤖 LLM 활용
|
|
**언제**: PR diff review, flaky test detection, commit message generation, changelog 생성.
|
|
**언제 X**: secret-handling pipeline (보안), production deploy gate (deterministic 해야 함).
|
|
|
|
## ❌ 안티패턴
|
|
- **Slow pipeline (>20 min)**: dev 매 ignore, "broken main" 정상화.
|
|
- **Flaky test 방치**: trust collapse → 매 retry, retry, retry.
|
|
- **No mainline protection**: 직접 push to main, PR 없음.
|
|
- **Build on developer machine only**: "works on my machine" 재현.
|
|
- **Secrets in logs**: env 출력, token leak.
|
|
|
|
## 🧪 검증 / 중복
|
|
- Verified (Fowler 2006 *Continuous Integration* article, GitHub Actions docs 2026).
|
|
- 신뢰도 A.
